There is not enought information. You said t is elapsed time, but you didnt say if it was in hours, minutes or seconds.
Which ever it is, convert 4 hours to the correct units (4 hours because the time difference between 5pm and 9pm is 4 hours) and plug that number into the equation.
Calculate the value for each of the terms and add or subtract them together, as appropriate.
The sum is the answer.
